Now that backtracking is working correctly, we need to avoid a
non-termination issue introduced by the [RelCompFun] definition in
RelationPairs, by adding a [Measure] typeclass. It could be used to have
a uniform notation for measures/interpretations in Numbers and be but in
the interfaces too, only the mimimal change was implemented.
Fix syntax change in test-suite scripts.

- New constr_expr construct [CGeneralization of loc * binding_kind *
abstraction_kind option * constr_expr] to generalize the free vars of
the [constr_expr], binding these using [binding_kind] and making
a lambda or a pi (or deciding from the scope) using [abstraction_kind
option] (abstraction_kind = AbsLambda | AbsPi)
- Concrete syntax "`( a = 0 )" for explicit binding of [a] and "`{
... }" for implicit bindings (both "..(" and "_(" seem much more
difficult to implement). Subject to discussion! A few examples added
in a test-suite file.
- Also add missing syntax for implicit/explicit combinations for
_binders_: "{( )}" means implicit for the generalized (outer) vars,
explicit for the (inner) variable itself. Subject to discussion as well :)
- Factor much typeclass instance declaration code. We now just have to
force generalization of the term after the : in instance declarations.
One more step to using Instance for records.
